NASA astronauts Terry Virts and Barry "Butch" Wilmore will perform a spacewalk outside the International Space Station Sunday (March 1), and you can watch it live here starting at 6 a.m. EST (1100 GMT). This spacewalk (scheduled to start at 7:10 a.m. EST) is the last in a series of three excursions to continue upgrading the station for the arrival of private space taxis carrying astronauts in 2017.

WEBCAST REPLAY: Searching for cosmic inflation
Scientists will talk about the search for signs of the Big Bang's incredible faster-than-light expansion during a live webcast Wednesday (Feb. 18), starting at 2:30 p.m. EST (1930 GMT). Watch it live in the window below:
In March 2014, a team of scientists using the BICEP2 telescope at the South Pole announced that they had detected a signal of primordial gravitational waves in the cosmic microwave background (CMB), the light that began saturating the universe 380,000 years after the Big Bang.
The announcement was met with a great deal of excitement. It seemed to confirm the basics of cosmic inflation theory, which posits that the universe expanded much faster than the speed of light in the first few tiny fractions of a seconds after its birth.
But last month, analysis of additional data collected by BICEP2, the Keck Array in Antarctica and Europe's Planck satellite showed that much of the purported inflation signal was actually caused by interstellar dust. Wednesday's webcast, which is hosted by the nonprofit Kavli Foundation, should give viewers insights into the current state of the search for primordial gravitational waves.
From Kavli: "Three pre-eminent scientists — George Efstathiou, Clement Pryke and Paul Steinhardt — come together to discuss Planck's latest results and what we can expect to learn about the very early universe in the coming decades."

HD Views from the International Space Station
NASA is now live-streaming views of Earth from space captured by four commercial high-definition video cameras installed on the exterior of the International Space Station. The project, known as the High Definition Earth Viewing (HDEV) experiment, aims to test how cameras perform in the space environment.
